Procedure

A suspension of 65 mg (0.165 mmol) of trans-(4-{3-[Ethyl-(2-hydroxy-ethyl)-amino]-prop-1-ynyl}-cyclohexyl)-methyl-carbamic acid 4-chloro-phenyl ester in 5 ml MeOH and 7 mg Pt/C 10% was hydrogenated (1 atm) for 16 h. The reaction was filtered (Celite) and evaporated. Flash column chromatography on silica gel with CH2Cl2/MeOH (9:1) gave 21 mg (32%) of trans-(4-{3-[Ethyl-(2-hydroxy-ethyl)-amino]-propyl}-cyclohexyl)-methyl-carbamic acid 4-chloro-phenyl ester, MS: 397 (MH+, 1Cl).
